Description

하수관 소음방지구{Device preventing noise in drain pipe} Device preventing noise in drain pipe

본 발명은 하수관 소음방지구에 관한 것으로서, 특히 아파트나 연립주택등 공동주택의 하수관내에 장착하여 하수관으로 흐르는 하수에 의해 소음이 발생하지 않게하는 하수관 소음방지구에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewer pipe noise prevention device, and more particularly, to a sewer pipe noise prevention device installed in a sewer pipe of an apartment house or a townhouse so that noise does not occur by sewage flowing into the sewer pipe.

아파트, 연립주택, 다가구주택, 다세대주택 또는 빌라등 공동주택들의 하수관은 합성수지 수직원통관으로 되어 있어서 하수가 흘러내릴때에 심한 소음이 발생하게 된다.The sewer pipes of apartment houses such as apartments, townhouses, multi-family houses, multi-family houses or villas are made of synthetic resin vertical cylinders, which cause severe noise when the sewage flows down.

그와같은 하수관의 소음을 방지하기 위하여, 도1에 도시된 바와같이, 중앙의 축봉(60)을 중심으로 축봉 외주면 전체에 스크류식 날개(70)를 형성한 것으로 구성된 하수관 소음방지구(110)가 개발된 바 있으나, 이를 하수관(10)내에 장착하기위해서는 건물에 설치할 하수관(10)내에 그 축봉에 날개가 형성된 소음방지구 전체를 삽입시킨 다음, 천정(80)에 고정된 연결관(20)과 바닥(90)에 고정된 연결관(40)에 상기 하수관 소음방지구가 내삽된 하수관(10)의 상하를 끼운 후 바닥(90)을 연결관(30)으로 나사결합(50)하여 하수관(10)을 고정하면, 소음방지구(110)의 하단(120)이 상기 바닥(90)에 고정된 연결관(40)내의 +자형이나 -자형의 받침봉(100)에의해 받쳐지게되도록 되어 있어서, 이와 같은 소음방지구(110)는, 축봉(60)의 외주면에 스크류식 날개(70)가 일체로 형성되어 있기 때문에 그 무거운 중량에 의해 운반시나 하수관내 장착시에 취급이 어렵고 중앙에 배수공이 없이 하수가 스크류식 날개부위로만 따라 흐르게 되어 오물에 의해 막히기가 쉬울 뿐 아니라 많은 양의 하수가 흐를 경우는 스크류식 날개(70)사이의 공간이 좁아서 쉽게 흘러내리지 못하고 넘치거나 막히는 등의 결점이 있게되고 또한 축봉(60)외주면에 스크류식 날개(70)가 형성된 소음방지구는 하수관(10)내면에 밀착되지 않기 때문에 건물바닥(90)의 연결관(40)내에 받침봉(100)이 없으면 지탱이 안 되고 흘러내리는 폐단이 있고 뿐만 아니라 소음방지구(110)와 하수관(10)이 밀착되지 않아 소음방지 효과가 없거나 적게되는 것이다.In order to prevent the noise of such a sewer pipe, as shown in Figure 1, the sewer pipe noise prevention device 110 consisting of a screw type wing 70 formed on the entire outer peripheral surface of the shaft centered around the shaft 60 in the center Has been developed, but in order to mount it in the sewage pipe (10) in the sewage pipe (10) to be installed in the building to insert the entire sound-proof ball formed on the shaft of the shaft, then the connection pipe (20) fixed to the ceiling (80) And the upper and lower portions of the sewer pipe 10 into which the sewer pipe noise prevention device is inserted into the connection pipe 40 fixed to the bottom 90 and then screw the bottom 90 to the connection pipe 30 by screwing the sewage pipe (50). 10) When the fixing, the lower end 120 of the noise prevention device 110 is to be supported by the + -shaped or-shaped supporting rods 100 in the connection pipe 40 fixed to the bottom 90 In this noise prevention device 110, the screw wing 70 is integrally formed on the outer circumferential surface of the shaft 60. Due to its heavy weight, it is difficult to handle during transportation or installation in sewage pipes, and the sewage flows only through the screw wing without a drain hole in the center, making it easy to be blocked by dirt and screwed wing when a large amount of sewage flows. Since the space between the 70 is narrow, there are drawbacks such as overflow or clogging, and the noise prevention port formed with the screw type wings 70 on the outer circumferential surface of the shaft 60 does not adhere to the inner surface of the sewer pipe 10. If there is no support rod 100 in the connection pipe 40 of the bottom 90, there is a closed end that is not supported and flows down, as well as the noise prevention device 110 and the sewer pipe 10 are not in close contact with each other, so that there is no noise prevention effect or less. Will be.

따라서 그와같은 좁은 공간에서 하수가 흐르게되어 공명현상이 발생하여 소음이 제거되지 않거나 소음방지효과가 적은 결점이 있었다.Therefore, in such a narrow space, the sewage flows, which causes resonance, resulting in defects that are not eliminated or have low noise prevention effects.

또한, 상기와 같은 결점을 배제하기 위하여, 도2에 도시된 바와같이, 하수관(10)내면에 직접 느슨한 스크류 날개(70')가 일체로 형성되고 중앙에는 하수공(60)이 형성되도록 성형된 하수관이 개발되어 시판되고 있으나, 이 역시 성형공정이 복잡하고 전체의 중량이 무거워서 운반이나 장착시에 취급이 어려운 결점이 있는데다가 이와같은 소음방지구 또한 실질적으로 하수가 흐를때 중앙공을 통하여 직접흐르면서 완충작용을 못하게 되므로 소음방지효과가 없거나 적게되는 결점이 있었다.In addition, in order to rule out the drawback as described above, as shown in Figure 2, the loose screw blade 70 'is formed integrally directly on the inner surface of the sewer pipe 10 and is formed to form a sewer hole 60 in the center Although sewage pipes have been developed and marketed, this also has a drawback in that the molding process is complicated and the weight of the whole body is difficult to handle during transportation or installation.The noise prevention device also flows directly through the central hole when the sewage flows. There was a drawback that there was no or no noise protection effect as it could not buffer.

본 발명은 상기한 바와같은 공동주택 하수관의 본래의 결점과 종래 하수관 소음방지구의 결점을 개선하여 건축물의 건축시는 물론이고 건축물이 완료된 후에도 수요자가 필요시에는 간단히 바닥(90)에서 하수관(10)의 하단을 고정하고 있는 연결관(30)을 풀어서 하수관(10)을 지붕(80)의 연결관(20)과 바닥(90)의 연결관(40)으로부터 분리한 다음 바닥에 눕혀놓고 한쪽끝에 갈고리가 달린 안내끈(11)을 하수관의 한쪽끝에서 다른쪽 끝까지 관통시킨 다음, 그 일측끝에 고정된 갈고리(9)를, 외부직경(외경)이 하수관과 같거나 더 큰 자바라식으로 절첩된 스크류식 소음방지구(1)의 한쪽끝에 형성된 갈고리공(4)에 걸어서 갈고리가 없는 끈의 타측을 잡고 잡아당기기만하면 자바라식으로 절첩되어 있던 스크류식 소음방지구가 길게 풀리면서 외경이 작아져서 하수관내로 들어가게되고 하수관의 반대편 끝까지 소음방지구(1)가 들어간 다음에는 잡아당기던 끈을 놓게되면 외경이 하수관과 같거나 더 큰 소음방지구는 스크류식으로 하수관내벽에서 계속하여 펼쳐지려는 탄력에의해 견고하게 지지되게되므로 하수관을 세우드라도 쉽게 빠지지 않고 하수관내벽에 지지된 채로 유지되게되며, 그렇게 하수관(10)내에 소음방지구를 장착한 상태에서 건물에 하수관을 다시 설치시에는 하수관(10)을 세워서 상기 분리시와는 역으로 건물에 결합하면 되므로 누구나 쉽게 하수관에 소음방지구를 장착할 수가 있고, 상기와 같은 소음방지구(1)는 하수관에 장착하기전에는 스크류식 날개가 자바라식으로 절첩되어 아주 간편하고 가벼운 형태로되어 있으므로 운반 및 보관이 쉽고 그것을 하수관에 장착시에도 양쪽을 잡고 잡아당기기만하면 쉽게 펼쳐지므로 장착이 용이하게되며, 하수가 그 소음방지구를 따라 흐를때에는 중앙공과 스크류식 날개를 따라 하수가 흐르게되므로 완벽한 소음효과를 얻을 수 있는 하수관 소음방지구를 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다. The present invention improves the original defects of the sewage pipes as described above and the defects of the conventional sewage pipe noise protection, so that when the consumer needs, as well as during the construction of the building, the sewage pipe 10 at the bottom 90 is simply required. Loosen the connection pipe 30 fixing the bottom of the sewage pipe 10 is separated from the connection pipe 20 of the roof 80 and the connection pipe 40 of the bottom 90, and then lying on the floor and hooked at one end Guide rope (11) with the penetrating from one end of the sewer pipe to the other end, and the hook (9) fixed to one end, screw type folded in a bellows type whose outer diameter (outer diameter) is equal to or larger than the sewer pipe Just hang on the hook (4) formed at one end of the noise prevention device (1) and pull the other side of the rope without a hook and pull out the screw type noise prevention device that was folded in bellows style, and the outer diameter becomes smaller. When the noise prevention device (1) enters the opposite end of the sewer pipe, release the pulling string, and the noise protection device whose outer diameter is the same as or larger than the sewer pipe is screwed and firmly supported by the elasticity to continue to unfold on the inner wall of the sewer pipe. Since it is supported, the sewer pipe is not easily pulled out and is maintained on the inner wall of the sewer pipe, and when the sewer pipe is re-installed in the building while the noise prevention device is mounted in the sewer pipe 10, the sewer pipe 10 is erected and separated. Shiwa is inversely coupled to the building, so anyone can easily install a noise suppression in the sewer pipe, the noise prevention device (1) as described above is very simple because the screw wing is folded in a bellows type before mounting on the sewer pipe Easy to carry and store because of its lightweight form It is easy to install because it is easily unfolded, and when the sewage flows along the noise prevention hole, the sewage flows along the central hole and the screw type wing, so that the sewage pipe noise prevention device can obtain a perfect noise effect. When described in detail with reference to the drawings as follows.

본 발명은 자바라형태로 절첩되어있다가 양측을 잡고 잡아당기게되면 일정폭을 갖는 스크류식으로 펼쳐지면서 그 중앙은 배수공(12)이 형성되고 당김을 놓게되면 탄성에 의해 원상복귀되도록된 절첩 및 전개가 자유로운 본체(1a)로 구성되고 그 본체의 일단부에는 본체를 하수관(10)내로 안내하기위한 안내끈(11)의 일단에 달린 갈고리(9)걸이용 갈고리공(4)과 두개의 결합공(2)(2')이 천설되며 그 단부 측면에는 미세한 수평돌기(7)가 돌출 형성되고, 상기 본체(1a) 타단에는 필요에따라 더 연결해야할 타 소음방지구 본체(1a)의 결합공(2)(2')과 대응 결합되는 두개의 결합돌기(3)(3')와 갈고리공(4)이 형성된 것으로 구성된 하수구 소음방지구(1)이다.The present invention is folded in a bellows shape and when the two sides are pulled and pulled to expand the screw type having a certain width while the center of the drain hole (12) is formed and folded and deployed to return to the original by the elastic It consists of a free body (1a) and one end of the main body hook (9) hook hook (4) and two coupling holes (1) attached to one end of the guide strap 11 for guiding the main body into the sewer pipe (10) 2) (2 ') is laid, and the fine horizontal projection (7) protrudingly formed on the side of the end, the other end of the main body (1a) coupling holes of the other noise prevention body (1a) to be further connected as necessary 2 'is a sewer noise prevention device (1) consisting of two engaging projections (3) (3') and hook holes (4) correspondingly coupled.

또한 상기 하수구 소음방지구(1)의 본체(1a)외에 그 하수구 소음방지구 본체(1a)를 하수관(10)에 용이하게 안내하기위한 보조기구로서 하부(6)는 원통이고 상부(6')는 깔때기형의 안내호퍼(Hopper)를 구비할 수도 있다.In addition to the main body (1a) of the sewer noise prevention device (1) as an auxiliary mechanism for easily guiding the sewer noise prevention body (1a) to the sewer pipe 10, the lower part 6 is cylindrical and the upper part 6 '. It may be provided with a funnel-shaped guide hopper (Hopper).

이상과 같이 구성되는 본 발명 하수관 소음방지구 본체(1a)는 하수관(10)내 전체에 장착될 수 있는 길이로 펼쳐질 수 있도록 한몸으로 성형하거나, 상기 소음방지구 본체(1a)를 짧은 길이의 단위체로 성형하여 여러개의 소음방지구를 그 일단에 형성된 결합공(2)(2')에 다른 소음방지구(1)의 타단에 형성된 결합돌기(3)(3')와 대응결합하여 하수관 길이에 부합할만큼의 길이로 소음방지구(1)를 연결한 후, 하수관(10)내에 장착시에는, 하수관(10)하단의 바닥(90)가까이에 결합된 연결관(30)을 풀어서 건물에서 분리한 다음 가로로 놓고, 도3에 도시된 바와같이, 하수관(10)의 일단부의 내측에서부터 그 일단에 갈고리(9)가 달린 안내끈(11)을 내삽시켜 그 안내끈(11)이 하수관(10)을 관통하여 그 안내끈(11)에 부착된 갈고리(9)가 하수관의 타단부밖으로 노출되도록한 다음 그 갈고리(9)를 소음방지구(1)의 본체(1a)일단에 형성된 갈고리공(4)에 걸고 안내끈(11)의 갈고리(9)를 걸지 않은 쪽을 잡고 잡아당기게되면 하수관(10)과 외경이 동일하거나 더 큰 소음방지구(1)의 본체(1a)가 스크류형태로 펼쳐지면서 외경이 작아지게되므로 하수관(10)내로 진입되게되고 그렇게 진입되는 소음방지구 본체(1a)의 일단이 끈(11)에 고정된 갈고리(9)에의해 하수관(10)의 일단부까지 진입되었을때 잡고있던 안내끈(11)을 놓게되면 소음방지구(1)의 본체(1a)가 탄력에 의해 자바라식으로 원상복귀하기위해 오므라들면서 외경이 커지게되어 하수관(10)의 내면에 소음방지구의 본체(1a)외경이 닿게되면 더이상 펼쳐지지 않고 지지고정되게되어 하수관(10)내에서 자연스럽게 스크류식으로 고정되면서 중앙에는 배수공(12)이 자연스럽게 형성되게 된다.The sewage pipe noise prevention main body 1a of the present invention constituted as described above may be molded into one body so as to be unfolded to a length that can be mounted on the entire sewage pipe 10, or the noise prevention main body 1a may be a unit having a short length. To the coupling hole (2) (2 ') formed at one end thereof to the coupling protrusion (3) (3') formed at the other end of the other noise prevention device (1). After connecting the noise prevention device (1) to a length corresponding to the length, when mounting in the sewer pipe 10, the connection pipe 30 coupled to the bottom 90 near the bottom of the sewer pipe 10 is released to separate from the building Then, placed horizontally, as shown in Figure 3, from the inside of one end of the sewage pipe 10, the guide string 11 with a hook 9 is inserted at one end thereof so that the guide string 11 is sewer pipe (10). ) So that the hook 9 attached to the guide string 11 is exposed outside the other end of the sewer pipe. Hook the hook (9) to the hook hole (4) formed at one end of the main body (1a) of the noise prevention device (1) and grasp the unhooked side of the hook (9) of the guide strap (11) and the sewer pipe (10) Since the outer diameter becomes smaller as the main body 1a of the noise prevention device 1 having the same outer diameter or larger is expanded in the form of a screw, the one end of the noise prevention device main body 1a that enters the sewer pipe 10 is thus pulled out. When the guide string 11 held by the hook 9 fixed to the end of the sewer pipe 10 is released, the body 1a of the noise prevention device 1 is elastic by the elasticity. As the outer diameter becomes larger as it retracts to return to its original position, when the outer diameter of the main body 1a of the noise prevention device touches the inner surface of the sewer pipe 10, it is not supported for further expansion and is fixed without being unfolded. The drain hole 12 is naturally formed in the center.

또한 이때 소음방지구 본체(1a) 상단의 외측면에 돌출된 돌기(7)에의해서도 하수관(10)내벽에 탄력적으로 밀착되어 스토퍼 역할을 하므로 소음방지구 본체(1a)는 스크류형으로 펼쳐져서 하수관 내벽에 고정되어 있는데다가 상기 돌기(7)에의해서도 더욱 견고하게 고정지지되게되어 소음방지구 본체(1a)는 하수관(10)을 직립으로 세우드라도 하수관(10)내벽으로부터 절대로 미끄러지거나 이탈되지 않고 견고하게 고정되게 된다.In addition, at this time, the noise preventing device main body 1a is elastically tightly adhered to the inner wall of the sewer pipe 10 by the protrusion 7 protruding from the outer surface of the upper end of the noise preventing device 1a, thus acting as a stopper. It is fixed to the inner wall and is also firmly supported by the protrusions 7 so that the noise prevention body 1a is firmly slid from the inner wall of the sewer pipe 10 without slipping or falling off even if the sewer pipe 10 is upright. To be fixed.

따라서 상기한 바와같이 기존의 하수관 결합방법과 동일한 방법으로 본 발명 소음방지구(1)가 내장된 하수관(10)은 건물바닥(90)에 고정된 연결관(40)내에 받침봉(10)이 없드라도 소음방지구(1)가 절대로 아래로 흘러내리지 않게되는 특징이 있다.Therefore, as described above, the sewer pipe 10 in which the present invention is installed in the same way as the existing sewer pipe coupling method is provided with a support rod 10 in the connection pipe 40 fixed to the building floor 90. Even without the noise prevention device (1) is characterized by never flowing down.

이상과 같이 구성되는 본 발명 하수관 소음방지구(1)는 사용전에는 자바라식으로 얇고 간편하게 절첩되어 있고 중량이 가벼워서 운반, 보관이 용이한 효과가 있는데다가 하수관(10)내에 장착시에는 펼쳐서 하수관에 스크류식으로 내장시키기만하면되므로 건축물 축조시나 완공후 아무때나 수요자가 간편용이하게 장착할 수 있는 효과가 있다.The sewage pipe noise prevention device 1 of the present invention constituted as described above has a bellows-type thin, easily folded, light weight, and is easy to carry and store because of its weight. Since it is only built in the way, there is an effect that the consumer can easily install it at any time during construction or completion of the building.
